Wooden pallet is used to carry goods

Wooden pallet is used to carry goods. When carrying goods, it shall be ensured that the wooden pallet is intact and has certain strength. There are two test standards to determine the strength of wooden pallet: one is bending strength test, and the other is drop test.

Specific test method: according to the form of simply supported beam, place the flat tray on the lower sleeper beam, align the inner side of the longitudinal beam of the tray with the two inner sides of the lower sleeper beam, and the spacing between the two inner sides of the lower sleeper beam is the support distance.

The lower sleeper beam for support is a rectangular empty box formed by butt welding of two No. 10 channel steels, and its length shall be slightly greater than the length of the tray. Then, two sleeper beams (upper sleeper beams) for loading shall be placed on the flange with a quarter of the support distance from the center line of the tray panel to both sides.

The two upper sleeper beams for loading are made of seamless steel pipe with outer diameter of 76mm and wall thickness of 6mm, and its length shall be slightly greater than the length of the tray. 3-5t compression testing machine can be used for tray bending strength test.

Other measuring instruments include dial indicator, moisture content measuring instrument, steel tape, plumb bob, etc. during the test, the tray is placed on the compression testing machine, concentrated load is applied on the upper sleeper beam through the pressure plate, and the loading speed is 10kg / s. when the load reaches 1.5 times the load weight of wooden tray, How to identify the bearing capacity of wooden pallet and measure the deflection of the middle part of the lower deck of the pallet. Fumigation free tray disinfection methods: drugs and heat treatment.

The drugs used are bromomethane and ethylene oxide
1. Stack the goods to be fumigated in wooden cases neatly, cover them with tarpaulin, compact the four sides and seal them, but leave a small corner for medicine.
2. Put a basin of clean water under the tarpaulin and next to the goods and put the medicine into the water.
3. Compact the drug discharge port reserved in advance to keep the goods to be fumigated in the wooden box completely sealed for 24 hours.
4. Open the tarpaulin for ventilation and wait for the poison gas to dissipate before moving the goods, about 18-24 hours. 5. Issue fumigation free wooden box disinfection certificate.
